XO-403 ★★[]
"VROOM! Engine powered up, ready for action!"
Introduction[]
Legend says war bots have been guardians of the crown for generations. Now the king and queen are abducted and with the princess missing, people in this land have forsaken this legend. However a Warbot that's been dormant for thousands of years is gathering strength in secret, and when he awakes, he will be the mightiest in the league.
Use on Your Team[]
XO is a very interesting hero. While both his damage and support (mostly healing) modes are effective, because they are dependent on random changes between modes it can be difficult to use him effectively on your team. On the other hand, he is also one of the more difficult healer's to take down; so when players manage to get enough soulstones to get him to 4 or 5 stars, you will see him frequently in defensive style teams.
