RoA Workshop: All Defeatable Workshop Bosses (I Can Defeat At The Moment)

After scouring through the Rivals Workshop to make a boss battle video, I've, yet so far, can beat only a handful of bosses. These were possible how I determined them on how easy it is to learn their movesets or they're boss-level, but there's a way to get over them.

Only a handful of bosses I was able to defeat, with a total of 5 so far. Here's the list:
Ronald McDonalds
Godkarmachine O Inary
Boss!Zetta
Abyss Hime
Beast Deity Hikaru (Technically I beat her, but I'll explain why)

Ronald McDonalds is... Well... Himself. How did this fucker get here?
Godkarmachine & Abyss Hime are taken by default and no further modifications used.
Boss!Zetta is set to Lvl. 1. It's considered harder than Lvl. 9.
Beast Deity Hikaru is activated by setting her CPU level to Lvl. 9.

There are 2 endings to fighting boss Hikaru, but I chose the pacifist route to get things through since the other ending is achieved by the normal boss fight. I thought I take it the other way instead of fighting her by being more pacifist to her. Also, the answer to "621 divided by 9" is actually 69, hence the "nice" answers.

Characters Used for boss fights:
Kragg (Ronald)
