nJoyUrAIDs you shall recieve Boomward, the geodude. Boomward is the explosive specialist of your band of assasins and must learn selfdestruct as soon as possible (you may replace with explosion when possible). Furthermore, Boomward is very vengeful and everytime an opposing pokemon makes him enter red health, you cannot switch and he must explode on them, taking them with him in the process.
(you may forgo exploding if Boomward is your last poke)

If you prefer: you can change geodude to Koffing (found in Celedon city if you Surf I think, but it's rare). Same rules apply but it'll know self-destruct when you catch it.

Additional challenges (optional), and in increasing order of difficulty

Boomward wants to prove to the world that it is the best explosive expert in the world. Any time self-destruct or explosion is used against you in the game (even if it was a wild pokemon), The next attack you use must be Boomward's exploding move.

Boomward may only evolve on time if it Solo's half of either misty's or erikca's team (you only need to succeed against one) without exploding moves (the fact that it must explode if red is still in effect here). If it fails, you must wait until learning explosion to evolve. (If you choose Koffing you must force it to stay a koffing until Soloing half of Blaine's or Sabrina's team. If it fails against both, you must wait until the pokemon league to evolve)

Every time Boomward explodes and fails to bring down the opposing pokemon (yes this includes ghost types), you must immediately go to the nearest pokemart and sell all of your revival and health potions (Boomward missfired and blew them all up) and cannot buy healing items again until the gym badge is obtained. If you have all gym badges, you must defeat the elite four to buy healing items.
