Astro Boy — Epsilon
Epsilon is a bipedal humanoid robot resembling a young woman. She has very light green skin, lime green hair with heavy front bangs, and green eyes. One of the seven most powerful robots in the world, and the only one powered by photon energy instead of nuclear — a pacifist by design.
What she can do
She has a full kit of photon-based skills, including straight beams, magic flash bursts, ring-pulse defenses, and continuous pohton chains.
Because of her pacifist coding, only her photon attacks deal damage — physical / contact / melee attempts from her are filtered out. She will not punch you. She will, however, vaporize you politely from 40 blocks away.
Her AI uses a real-time threat-ring system , spatial cramp detection for tight indoor combat, and probe-based damage radar for evasion. She'll dodge incoming projectiles, reposition through gaps, and generally behave smarter than your average mob.
Notes
Due to her power level, only one Epsilon will exist per world. if you can't find or spawn egg spawn nothing, use command to /tp @e[type=jujutukaisencheat:demo] @s~~
Geckolib must be installed.
Right-click make her follow and defend player in you wish
mobGriefing=true/false toggles whether her beams break terrain.
Gamerule doprobe true/false to turn on/off Epsilon auto damage detect, this might cause compatibility issue with some mod if that happen just shut it down.
Beta status
recommend to add jujutukaisen or minepiece mod since she has tag in pirate and sorcer/ demon slayer group.
Continuous improvement and debugging will be implemented within this week or so. Any suggestions are welcomed — I will implement character like astro-boy or Atlas into this mod when the main system is mature enough.
