a huge Kat ghost that is made of shadows (like a larger Grimalkin spookat but with red eyes) that floats around a platform shooting multiple types of energy balls and summons 5 other cat Kat ghosts by doing a creepy mew sound. after a certain amount of damage it will dash bite across the platform. to hurt it the knight team must light a couple candles on the platform near its location on the platform to stun it with fire balls on center of the platform.
floor feel: ghost castle areas, boss room lit up by candles when knights stand on party switch the lights blow out and the spookatzilla rises from the darkness.
Sounds like a candlestick FSC. lol, if it were T1 it would be interesting enough, but we already have a undead boss surrounded by undead, having this would be alright I guess, but they should focus on making bosses of types that haven't been used, like a gremlin boss. Also, Spookatzilla is kind of a corny name, I would suggest some sort of giant grimalkin with a more original name. I think bosses like Tinkenzar should come out first, so that they have a boss for every type. We don't have a fiend type boss either, even though Vanaduke has a weakness to pierce like a fiend, on the wiki it says that lore leads to believe that he is undead. It would, however, make candlestick keeps have more of a purpose in the story line, since missions are coming out soon they are going to have to have some sort of way to make candlestick keep missions, and if they have no purpose in the story, it wouldn't make any since.
