Always remember BW Ghetsis, the one and only true final boss of a Pokemon game, items equipped? check, high bst mons? check, opens with a stall mon capable of checking one of the dragons or ruining a starter? check, uses high bst moves with decent accuracy such as afro break bouffallant? Check!
And finally hydreigon with near perfect coverage and LO at a decent level without the stupid spikes of Red and Cynthia.
Seriously it's just pure genius stuff, the game gives you all you need to beat him, the battle is fair and instead of relying on level spikes or weaksauce distribution like Red snorlax having a weakness to one of the rarest stabs in GSC makes Ghetsis a true final boss.
I know, Benga and the super bosses have higher levels and all, but Ghetsis is such a well thought battle they had to steal arceus drums to make it justice.
It makes us realize how mediocre other generations actually where when we get something that is actually good.
1. You forgot Evice from Colosseum, who is just as hellish as good old Ghetsis, if not moreso, given the lack of stuff you have to handle his top tier mons.
2. And yes, Ghetsis was probably my favorite final boss of any Pokemon game. a perfect, climactic battle that was a fair kind of difficult (and then came BW2, where he got nerfed to oblivion, and marked the start of the downward spiral of difficulty, until we now end up in ORAS)
Which brings me to another thing I forgot to mention, or rather, two other points of annoyance: The rematch rosters of the Elite 4 and Steven are... lolsy, at the very least. Remember back in Gens 4 and 5, where Gym Leaders/Elite 4 members in their rematches had hold items on their mons and actual dangerous movepools? Yeah, no hold items here, because "We making things easy for the kids", and no dangerous setup sweepers around. Glacia's arguably the most dangerous, both initial fight and Rematch, but only because constant hail making your attacks hit, and her Blizzards always hit. Everyone else either has average moves on their mons, with almost nothing above 90 attack power, or said strong moves... on really weak mons (Brave Bird Mandibuzz, ladies and gents). Drake's team especially suffers because of this, lacking any DDancers whatsoever, when Haxorus, Salamence, or even Altaria could easilly carry it, plus a physical movepool for the latter, and be terrifying. And whoever was the one that gave Steven Stone an OFFENSIVE CARBINK needs to be shot. That's just... lame, on so many levels. I know ORAS is meant for a younger generation than I, but it still kills me to see such rematches squandered and made... pathetic, really.
And secondly, is the "Okay, time to fast travel to this place!" segments. When I beat Team Aqua/Magma at Meteor Falls, and Flannery in Lavaridge Town, atleast it was optional for me to be warped right to my destination, which let me go clean up stuff in the immediate area, but once I beat Norman? NOPE, HERE COMES WALLY TO WARP ME OVER TO MAUVILLE CITY, WHEN I WANT TO GO SURFING AROUND DEWFORD AND AUUUUUUUGH! This railroading is just annoying, especially when R/S/E had none of it, and no one complained back then.
