This Alien Evolution addon adds a large handful of DELTARUNE-related powers and items. Most notably, four (two secret) transformations and one item:

Ralsei Transformation

• Fluffy boy, low HP but can heal others or himself.
• for the bit, has a cigar he can smoke to inflict status effects onto opponents.
• Can ACT to increase his Tension Points, which lets him use his healing magic.

The Roaring Knight Transformation

• Extremely powerful
• Variety of attacks such as shooting out star projectiles which explode into arrows
• Can summon a strong blade, however cannot detransform until it has been retrieved.

Devil's Knife Weapon

• Scythe, cut and swing, swing!
• Uses voicelines from the Jevil bossfight for the moves to feel more dynamic and active
• Quite powerful, making the user evasive also.
• Obtained using 3 key pieces from across the 3 base minecraft dimensions.

2 "Perfect" aliens hidden in the code. Only one has full powers and function, the other has mostly customizability.

That is all for v0.1, the first version. I have worked on this addon for about 5 months now with an associate, @dogedude1234 on discord (Credits to most item models, most item powers, and some help with concepts/designs).

DELTA: Evolution, a silly little mod made by two people. This mod adds things like, the roaring knight as a transformation in alien evolution, the Devilsknife, a very powerful and menacing weapon, and ralsei, a goat who smoke.
