Based on the Minecraft 26.3 / NeoForge branch. Values describe the shipped defaults; server configuration and wave scaling can change combat stats.
Combat profile
For Minecraft 26.3 / NeoForge, wave base values and supported behavior can be changed per registry entry: see health, damage and base armor and mob abilities. Tier, size and wave scaling still apply.
Entity ID: invmod:fat_zombie. This is a separate mob from the Zombie Brute: its defining mechanic is feeding rather than the Brute’s charge.
Feeding and growth
A Homer variant appears on 1% of initialized Fat Zombie spawns. It has a unique model, visible name, doubled movement speed and only its “D’oh!” hurt sound, while keeping all feeding rules. Variant state survives reloads.
When ready to eat, it selects the nearest living IM mob within its feeding radius, initially 2 blocks. The target need not belong to the same Nexus. It does not indiscriminately eat every vanilla or foreign-mod mob. The victim is removed immediately, without normal death loot.
Eating lasts 32 ticks (1.6 seconds at 20 TPS). During this time it stops horizontal movement, suspends its attack and mining goals, and rejects incoming damage. Its 200-tick feeding cooldown (10 seconds) starts when a meal begins.
After eating, the victim’s remaining health is added to both maximum and current health. The attack value is set to 18 + completed meals. Each meal adds 0.05 to its growth scale: after four meals it is 1.20× its original size, and its feeding radius is 2.4 blocks. Growth is additive, with no explicit meal cap.
Separate it from other invaders and attack between meals. A packed crowd can turn it into a much larger threat.
Equipment and terrain
It attacks players, Iron Golems and tamed Wolves, and advances on the Nexus. Mining is enabled by default. It cannot use armor slots; its defaults also disable starting weapons and armor. It can still pick up a weapon when not already holding one, or a suitable shield. A held ranged weapon enables its ranged attack goals.
Spawning and waves
The dedicated egg is invmod:fat_zombie_spawn_egg, using vanilla Zombie egg artwork. It is an active, non-boss wave option by default, with base cost 30 and themes SWARM, MIXED, RANDOM, RANDOMHELL, BRUTES and UNDEAD.
Selection depends on the phase theme, budget and server configuration; it is not guaranteed at a fixed wave. RANDOM and RANDOMHELL use their special cost rules. See Waves for starting an invasion. There is no dedicated natural vanilla replacement for this variant.
Drops
Uses the vanilla Zombie loot table: Rotten Flesh, with conditional rare Iron Ingot, Carrot and Potato drops. Looting and player-kill conditions follow vanilla rules. An independent IM roll also gives 1 Small Remnants with 25% probability.
