Omega Flowey Fight Simulator

Quick start

This fight needs a keyboard. It will not play on a phone. Press Play, then click the game so the keys reach it.

Arrow keys move the soul. Z confirms, including FIGHT. Press T for a secret. The instructions hint at it with Temmie flakes, and they say there are two secrets to find.

pp920921 warns that the project lags and has bugs. The instructions also say fullscreen ends the fight. The Fullscreen button on this page only makes the frame bigger. If the battle ends when you use it, press Restart once the fight has started, then click the game again.

The Omega Flowey boss

This Flowey boss fight is the long battle at the end of a Neutral Route, after Asgore. It is not the short meeting in the Ruins. Flowey takes the six human SOULs, the save screen breaks, and the fight begins.

Undertale never prints the name Omega Flowey. Players also call this form Photoshop Flowey, from a line in the Neutral Route credits that can be read more than one way. Omega Flowey is the name on Fangamer's tarot card, and the name Everdraed, who co-designed the battle, has used.

How the attacks come

The original battle is not the normal turn menu. You dodge, and FIGHT and ACT appear at certain moments. During the fight you have 50 HP no matter your LV. Six SOUL segments interrupt the attacks. In each one, ACT calls for help and the shots turn into green healing patterns. After all six, defense drops to 0 and the attacks simplify.

• Phases 1 and 4: the lower eyes fire seven X-shaped bullets, the upper eyes fire triplets, short flamethrower bursts appear, a warning circle closes into pellets, vines aim at the soul, and a mouth beam can follow the vines.
• Phases 2 and 6: a flytrap pulls in flies, bombs fall from above, shots come in from the sides, and three bouncing dentata cross the screen.
• Phases 3 and 5: only the upper eyes and the vines, plus a SAVE labeled FILE 2 that can reload and catch you after a dodge.

Each SOUL segment uses imagery from that human's weapon: knives, hands, shoes, books, pans, and a gun. After ACT, those shots turn green and heal. In this project, Z is the key that confirms FIGHT and ACT when they are on screen.

What this project includes

pp920921 marks Omega Flowey's attacks for phases 1 through 6 as finished, the soul attacks for phases 1 through 6 as finished, and the finale as finished. A sequence titled You IDIOT is about 75% done and still in progress, so treat that part as incomplete.

Expect lag and bugs. That warning is on the project itself.
