We All know what happens when lightning strikes on a pig, or a creeper. On a pig, it turns into a zombie pigman, a creeper, a charged creeper. Well wouldn't it be cool if when you strike lightning on other mobs, it transforms or changes into something else? Right now, what happens to the mobs (excluding pigs and creepers) when struck is...get ready, they die. It's really boring that nothing happens to them, why are creepers and pigs so special? I hope in later updates, Mojang will add some creative ways on how mobs will change once struck. I made a possible list on what will what mob change into what, not a very good one, you guys can comment and add suggestions on what you think what should change into what.

Chicken -> Evil Chicken ? (red eyes and starts flinging deadly explosive eggs)
Cow -> Cowman ? (like zombie pigman)
Ocelot/Cat -> Sabre Cat ? ( Huge cat with big fangs )
Sheep -> Multicolored Sheep (Sheep with pelt of all wool colors)
Squid -> A Kraken! ( haha )
Villager -> Villager Zombie ? (just like a zombie but with villager scheme)
Wolf/Dog -> Werewolf (Like in that mod)
Enderman ->
Spider/Cave Spider -> Spider Queen (assuming that all spiders are female and spawns spiders and turns into a big spider with a woman head)
Silverfish -> Shark Piranha (A huge fish with a huge mouth that will eat you up)
Skeleton -> Summoned Skull (YU-GI-OH)
Slime -> SludgeMan (Humanoid Slime)
Zombie -> Steve (idk)
Iron Golem -> Back into jackolantern and ironblocks
Snow Golem -> Back into jackolantern and snow blocks

Comment some suggestions and ideas about what could be possible transformations...be as creative as you can be!

(DID NOT INCLUDE NETHER MOBS :D )
