Typhlosion has been known for quite a few Pokemon gens to be sadly sitting in the shadow of its Fire-type starter predecessor in Charizard. Typhlosion has the exact same stats as Charizard, with the only relevant competitive differences being in movepool and secondary typing. Charizard makes use of its secondary Flying-typing and access to Belly Drum in particular to carve itself out a niche in GSC OU as a dangerous Ground-immune sweeper featuring the excellent QuakeSlide physical coverage alongside Fire Blast to tear through most of the tier after a Belly Drum. Typhlosion, on the other hand, did not receive Belly Drum, and only has Thunder Punch as well as an Electric neutrality and 1x Rock weakness to compensate for these shortcomings. Charizard itself is a fairly rare sight in serious GSC OU games, and with Typhlosion offering even less than Charizard, Typhlosion is essentially never seen in OU games, or even in UUBL games for that matter. As such, we should consider whether Typhlosion would be an appropriate and beneficial addition to GSC UU.
Strengths
Typhlosion presents some attractive qualities for the tier; its Base 100 Speed is much more impressive in UU than in OU, outspeeding many important Pokemon already considered fast for the tier, like Haunter, Mr. Mime, Gligar, Pinsir, Gyarados, Blastoise, and Nidoqueen. Typhlosion would be able to back up its threat against these Pokemon with its excellent combination of STAB Fire Blast, great special coverage in the form of Thunder Punch and Hidden Power Grass, and mixed attacking potential via Earthquake and Dynamic Punch. Additionally, Typhlosion's decent bulk for the tier could allow it to stomach an attack to set up Sunny Day instead of running a coverage move, which could amp up its Fire Blasts to levels that make even resists think twice about switching into it, reduce the threat posed to it by the tier's many Water-types, and even support teammates by reducing the accuracy of enemy Thunders. Typhlosion's decent bulk and Fire STAB could give it an important defensive role in checking the Bug-types of the tier as well; Scyther is at high risk of dropping to Fire Blast in one hit, while Pinsir is always OHKO'd by it. Meanwhile, Typhlosion always survives even a +2 Hidden Power Ground or Double-Edge from both Bugs. Defensively, Typhlosion's mono-Fire typing doesn't seem like it would offer too much else, but the neutralities the type offers means that Typhlosion could be used to switch into Pokemon like Hypno, Mr. Mime, and Haunter relatively safely if the situation calls for it - perhaps even the tier's Electric-types in a pinch as well.
Weaknesses
Typhlosion presents a number of issues for any UU player trying to place it on a team, however. As mentioned above, GSC UU is filled with Water-types, and fairly bulky ones at that. Typhlosion's fellow starter Pokemon Blastoise in particular seems like it would be its greatest roadblock; Thunder Punch and Hidden Power Grass do relatively little to Blastoise and require prediction to land on the switch. Blastoise in turn sports STAB Surf and RestTalk to make progress difficult for Typhlosion. While other Water types in the tier seem like they would be less solid checks, being more fearful of Typhlosion's coverage and power, they would likely still make Typhlosion think twice about using Fire Blast. This would be a huge detriment to a Pokemon that would likely be quite difficult to switch in safely and one which might have difficulty running a RestTalk set of its own, compromising its longevity. Beyond Water-types, the tier's infamous bulk might make it harder for Typhlosion to make progress than it would seem, especially against Pokemon like Nidoqueen, who packs STAB Earthquake and Moonlight, and Hypno, who could conceivably frustrate Typhlosion's attempts to KO Hypno with inaccurate Fire Blasts via RestTalk. Finally, there is the issue of trying to fit Typhlosion on a team, given its lack of defensive qualities mentioned above. GSC UU builders are crafty and might find ways around this, such as using Typhlosion in the lead slot or fitting it on Swords Dance + Baton Pass teams, but the lack of resistances and many weaknesses to popular attacking types would probably still limit the amount of teams Typhlosion could function consistently on.
Possible Sets

Typhlosion @ Leftovers
Hidden Power: Grass
IVs: 6 HP / 28 Atk / 28 Def
- Fire Blast
- Thunder Punch
- Hidden Power [Grass]
- Earthquake / Dynamic Punch
This is the most straightforward application of Typhlosion, as a mixed attacker with high power on STAB Fire Blast and excellent coverage. Thunder Punch and Hidden Power Grass threaten every Fire resist in the tier, while Earthquake provides a stronger hit on Electric- and Poison-types, particularly those with good special bulk. Dynamic Punch could be run instead of Earthquake for physical coverage to hit Chansey if the team is less worried about Electric-types like Ampharos and Lanturn. This set's primary issue would be lack of longevity due to no recovery. It might also struggle to threaten some bulkier Pokemon if Spikes can't be maintained. This could be an issue against stall teams in particular, which pack Blastoise and Pursuit trapping to make keeping Spikes up difficult, as well as Shuckle, which is not 3HKO'd by Fire Blast.

Typhlosion @ Leftovers
IVs: 6 HP / 28 Atk / 28 Def
- Sunny Day
- Fire Blast
- Thunder Punch / Hidden Power [Grass] / Dynamic Punch
- Hidden Power [Grass] / Thunder Punch / Dynamic Punch
The Sunny Day attacker. This set would trade some coverage for the power and Water damage-reducing ability of Sunny Day. Checks like Nidoqueen and Hypno would be easier to break through, in exchange for dropping coverage against some of Typhlosion's other checks like Gyarados, Quagsire, and Chansey. Just like the above set, this Typhlosion suffers from lack of longevity, although it has somewhat less of an issue with this when Sun is reducing the power of incoming Water-type attacks.

Typhlosion @ Leftovers
- Fire Blast
- ???
- Rest
- Sleep Talk
Could a RestTalk set work on Typhlosion? I honestly don't know. The ??? moveslot is hard to figure out. Perhaps Roar for shuffling around the threat of Typhlosion's Fire Blast, or one of Thunder Punch / Hidden Power Grass for coverage? This set would mitigate Typhlosion's longevity issue, but would reduce its offensive capabilities. Typhlosion seems to me most effective when it is taking advantage of its Speed and coverage, so I am somewhat doubtful about a set like this, especially when you consider that RestTalk Arcanine has not been a successful set in GSC UU despite its higher bulk. Who knows, though!
Conclusion
At the moment, we don't know how good Typhlosion would be in GSC UU or whether it would be a healthy addition to the tier, and I believe it is the next UUBL Pokemon after Aerodactyl and Muk that should be put through serious tests to see if it is worth dropping to UU. This thread will act as discussion for this idea, where we can make arguments about Typhlosion in GSC UU and back them up with solid evidence of Typhlosion teams and replays. I'm looking forward to what we find!
