The ogre is a 20m tall dark green boss mob that looks like a poor reconstruction of a T. rex. It has 3 pairs of tusks (2 pairs on the bottom, with another pair between them, on the top), a beard, obsidian textured armour on the top of the head, with brow horns and 2 nose horns (like tetraceratops), giant, muscular arms, bedrock textured boots, an upright stance, and a dragging, spike-covered tail. They are immune to fire, posion, the wither effect and to attacks to the head armour or boots. Their feet and tail destroys blocks that tnt can destroy, and they can jump 33796m. They chase villagers, illagers, zombies, skeletons and players, and grab and eat them when they catch them. They cause an aura of green potion particles, which also destroys organic blocks, destroys organic based items, and causes the wither effect, posion, nausea and hunger. It can breathe something similar, whichis much more powerful, and can destroy any block (except obsidian and bedrock). They drop ogre boots, and lots of pork, and drops of the mobs it chases. ogre boots cannot be worn, but they can be crafted into jump cores, which can be used with the elytra as fireworks, but the blasts are longer, faster, and the jump core is reuseable. The ogre is spawned by throwing a totem of undying into a fire, making it spawn where it would be just out of sight, if on the lowest setting.
This suggestion is extremely unbalanced and random. 20 meters is twice as tall as a Giant, and the distance it can jump looks like your cat stepped on your keyboard to determine it. Ever seen neural networks attempt to create movie titles or recipes? That's what this suggestion looks like; it's nonsensical, has no regard for theme or balance, and looks to have been slapped together out of vaguely suggestion-y parts.
This mob would literally decimate worlds in a fashion that makes very little sense. It's also insanely overpowered (being able to inflict 3 potion effects at once, one of which is Wither) and its drop makes literally no sense whatsoever.
I have answered/fixed all of your genuine problems with this suggestion
All of them were genuine problems, and, even if the drops are different, this suggestion is still a mess.
It does not matter whether this suggestion's flaws are "intentional". They're still flaws. Arson and electrical fires ultimately have the same effect; so it is with this. Even if it is supposed to be "toxicly noisome" (spell check is NOT your enemy) it is still horrendously overpowered, impractically huge, ridiculously destructive, and overall just no fun.
Just as this suggestion is still basically the same, so is my opinion of it: No support.
Make the ogre less overpowered, but I like how you summon it. The ogre should drop an ogre heart upon death instead of a jump core hich isn't much different than fireworks. It would be more original. When eaten, the player ets the growth status effect. They grow to 4 meters tall and do 1.5x as much damage. When they touch a player, they do damage even when not attacking them.
If this mob were to be implemented, i feel as if it would be avoided just because of how OP it is. Having a mob that is almost 10 times the height of the player that can jump extremely high would be something that would be harder to kill than the dragon and the whiter bosses, not to mention its attack itself.
This boss is way too overpowered for a game such as minecraft.
