Killer Apps?

[ghost master]

Out of the current group Ash, May, TR, Max and Brock what pokemon that they have do you consider to be Killer Apps. By killer apps I mean the incredibly powerful pokemon. Charizard and Squirtle are considered apart of Ash's team still since he can call upon them whenever he wants to. Here's my list.
Ash-Pikachu, Charizard, Bulbasaur, Kingler, Muk, Tauros, Snorlax, Heracross, Swellow, Grovyle, and [SPOIL]Glalie[/SPOIL]
Brock- Ludicolo (although its not a killer app its his strongest I believe. Onix and Crobat dont count anymore because there Jiroo's)
May-Beautifly, Combusken, Skitty. [SPOIL]Squirtle is a good appealer but, I dont think its had enough time to prove how good it is or bad. Munchlax has awesome moves but, hasnt had an official battle yet but, the upcoming episode will prove.[/SPOIL]
TR-Seviper(its their strongest)

 

[Kabuto]

[SPOIL]When Grovyle evolves, It'll be Ashs killer pokemon[/SPOIL]

May is obviously Combusken

As for Brock I'd probably say Forretress

Team Rocket is Seviper

Erm...

Ash - Pikachu (duh), Charizard (only fully evolved 3 stage Pokemon, Snorlax (basically a tank). Maybe also Kingler (look at Indigo League performance), Heracross (look at Johto League performance), Swellow (the ultimate resistant machine) and [SPOIL]Glalie (look at Hoenn League performance)[/SPOIL]

Brock - Eh...Onix would have been, but he doesn't have it anymore...possibly Forretress then.

May - Can't really call hers killer, Combusken is probably her most powerful.

Jessie - Seviper. Wobbuffet would also deserve a mention but is rarely used so we cannot see its potential.

James - Erm...Cacnea, since its his ONLY battler.
