The Cuphead Souped Up mod is an incredibly difficult Cuphead mod that gives bosses some new attack patterns, makes them faster, and gives them way more health. There's also a stat rebalance of the weapons in the game to nerf some of the most powerful weapons and buff some of the under utilized weapons to allow more versatility in weapon choice for each boss.
Dr. Kahls Robot might possibly be the most difficult boss in this entire mod. Each phase requires figuring out a very specific strategy in order to minimize your chances of taking damage. Even though it looks relatively straightforward, 1st phase requires a lot of small optimizations in order to bait the laser while staying out of the pattern of the miniplanes. It's also very important to try to defeat all 3 robot parts close to the same time to expose the heart, as it gets extremely difficult to dodge attacks when they get mixed from the first part of 1st phase and the second part of 1st phase. Final phase is a completely different beast, as it is a pure bullet hell with incredibly tight patterns to avoid taking damage.
