P.S. I have made the plot for season 3 & 4, In three it is a team tournament like big bang bladers(I will post the teams, I will take suggestions) and season 4 Akiba's bey Khaos(Look at season three and you'll see what I mean) is summoning other lords of khaos. I will update this in the future.
Sure, but the main evil team in season three(This is for season three right?) is the DoomReapers. That and each team is made not by country. I will repost my post about it here. Of course, if that is fine with you. Not to mention Akiba is the main Antagonist for the entire series, with first Demon Balthazar, then Gaia Typhon, then in season 3 he gets the Lord of Chaos and Protogentoi of the Void, Void Khaos and his synchrome for this bey, Typhon Khaos. In season 4, Khaos takes control of Akiba and "Embodies" Akiba, Using him to unleash power. That power begins to revive the great Lords of Khaos through Beyblade, but for each Lord of Khaos(Including Khaos) there is one Lord of Order(Also known as Bladers of Order) that is the counter-part of a certain Lord of Khaos and is the only one who can defeat him/her in the final battle, where Khaos will try to destroy the world by devouring it with the void. I will write the Lords of Khaos and their Lord of Order counter-part later, and Nemesis will return as a Lord of Khaos. Remember, Akiba was not defeated in the end of season two, he survived and is still the main evil.
Known Lords of Khaos:
Let me know what you think, I personally like it, just let me know. Let me know any suggestions you have, and this is just between you and me to choose.
For Season 3: The teams are made via one person getting with 2-4 others to form a team. The only qualification is that the teams must compete in one of 4 team tournaments and the top 8 in each tournament will compete in the world championships. There are 4 Blocks in the tournament: Block A, B, X, Z. The Team Leader DOES get to choose who he wants on his team, and CAN make it only for people from a certain country. Thats what the best part about this world championships is.
