Gargantua Zombies

A Zombie who's Giant, does a high amount of damage, (Maybe a little less than pigmen, or more.) and is a rare spawn.

Giant Zombies were originally meant to be added, and could be spawned in with commands.

I think Minecraft is very lacking of rare, difficult challenges. And if a Zombie Gargantua was added, it should reward the player with a lot of XP, or a certain drop. Or maybe none at all, but even then it would be a great addition.

I don't think it should look like the old Giant Zombie, like shown in the image, instead I think it should be given a whole new model. A Zombie Gargantua. Wide, tall, deadly.
