I don't know, but he was my favourite when I first played Bomberman 64 and needed to fight against him. He was very awesome from design and characterism. He frightened me in TSA after I saw him the first time, but I barely remembered him in his original blue designed armour. He really changed, but still in some way he was the same person as he was before TSA. Don't know how to say it xD
I have plenty favourites, but when it comes down to 1 Elemental Knight, then it's Bulzeeb for sure :3
lol, nobody voted for Behemos or Molok. I guess nobody likes old people I think Molok is one of the toughest bosses. I mean I can kick Regulus' sorry ass in less than 30 seconds (I even made a video about it)
...but Molok... he is hard. Especially in the japanese version of the game. That Rock Breaker move is harder to dodge when you're moving slower, and deals twice the amount of damage. I sometimes get very lucky fighting him, sometimes really unlucky. I wonder how hard he would be with only 5 hearts. ._.
Well, I do like Behemos, Sadly he doesn't get a vote since Regulus was in 2nd attack, but Behemos is my next favorite astral knight, beaten only by Bulzeeb/Regulus
