you need the item link cable
After you evolve in Pokemon Mystery Dungeon, you should train to level 100 then kick other pokemon's ASSES
yes all Pokemon evolve in Pokemon mystery dungeon blue rescue team after you beat Rayquaza and legendary Pokemon don't evolve.
The item needed for Kadabra to evolve into Alakazam is the Link Cable. The Link Cable is found in Solar Cave on The 10th floor and you need a key to get it!!! Hope this helped!!
All Pokemon evolve at the same level in Pokemon Mystery Dungeon as in the other games. As such, Treecko is able to evolve at level 16 in Mystery Dungeon. However, evolution is only unlocked when you get far enough in the story.
to evolve you have to get palkia and unlock marine resort
it will evolve into a better Pokemon
In Pokémon Mysery Dungeon: Blue Rescue Team, you will need to recruit Kadabra in the Buried Relic, Wish Cave or Solar Cave and then you will need to go into Luminous Cave with just Kadabra in your rescue party as well as a Link Cable in your possession and it will evolve into Alakazam.
you can evolve your starter pokemon
It depends what you mean by "hero Pokemon"
You keep going to the end and then you can evolve
Absol doesn't evolve.
darkria is a legendary, so it DOES NOT evolve.
