To'kustars are extremely rare aliens, who are probably the most powerful in the universe because they are gigantic. They are created in unpredictable, extremely intense cosmic storms. They are extremely strong, but not as durable as their size may come to think. They are one of the most powerful alien species in the universe. Since they are created by cosmic storms, they have no true home planet, but they find shelter in a variety of suitable planets. The creator of the Omnitrix, Azmuth, programmed a To'kustar's DNA Ben later named Waybig into the Omnitrix to battle Vilgax and his army. Then, in "War of the Worlds" Azmuth let Ben regained his old forms and he used Waybig again. In "Ken 10" Waybig was used also, so Ben 10,000 could mercilessly pound Kevin 11,000, though that episode was considered non-canon. The To'kustar to the right is Waybig. The Omnitrix symbol is an addition since this is the Omnitrix form, and it is unknown if there are any other modifications.
