Not all Pokemon require you to battle and level up to battle.
For those that do, Rare Candies can usually be a simple method of levelling up quickly.
No but if you wish to complete your pokedex without filling up the storage boxes you must and evolving is alot easier and cheaper to do than caching one of every stage. remember if you don't want a Pokemon to evolve just make it hold an everstone
Togepi can evolve into Togetic at any level depending on how happy it is. In order to increase Topgei's happiness, it'll need to keep on battling and you can also give it vitamins such as Protein and Iron.
Axew evolves into Faxure at lv.38. Then at 48 into Haxorous.
pokemon do not evolve on pokemon colosseum
Level it to level 36.(without it holding a everstone)
Evolve Feebas
Well you can get an action replay and use that or just keep battling trainers, not Pokemon. Battling Pokemon is slower than battling trainers.
not until the battle is finished!!
train it untill its level 25. keep battling it with pokemon it can manage.
It won't evolve without trading
No, you must trade the certain Pokemon that need to be traded to evolve to make them evolve.

If you mean evolve, then keep battling with your Pokemon with other wild Pokemon or with other people in the game, so you get exp and then level up until it says, "What, so-and-so is evolving!"
It depends on the Pokemon you're trying to evolve. While some Pokemon can evolve without any problems due to being in the regional Pokedex, other Pokemon (Golbat, for instance) won't evolve without the National Pokedex. Note that this is only the case in FireRed and LeafGreen - in later games, Pokemon not in the regional Pokedex will evolve, but won't be recorded until you get the National Pokedex.
You have to evolve a Chansy by making it happy, u can do so by battling with it, feeding it Vitimans, or getting it to hold a soothe bell.
no, you have to trade them.
Pansear cannot evolve without a firestone... ^_^
