Unfortunately not a very common sight among trainers, but it still has its uses. For example, Raichu can hold up to 100 000 volts of electricity in its cheeks, and is otherwise stronger then the speedy Pikachu.
Since the other johto starters got a mega i thought Typhlosion deserves one as well, so here is my idea for a mega for it. It's been quite some time since i made a new pokemon so it feels quite refreshing, hope you like it
Pikachu has the ability to shoot electricity, which is stored in its cheeks. Using electricity on another one of its kind can recharge them to full health.
