The answer is Bowser, Eggman, Bowser Jr, Metal Sonic.
from the left, bowser eggman, bowser jr., metal sonic.
Bowser, Bowser Jr., Metal Sonic and Dr. Eggman.
Bowser Jr., Metal Sonic, Bowser and Dr. Eggman.
bowser,dr.eggman,bowser jr,metal sonic
just click on them but if you are playing it on the nentendo then no cant
the new characters are...silver,metal sonic,donkey Kong and bowser jr.
If you mean in Adventure Tour on DS, they are in Blitzland. You need to get through a puzzle of pipes with Mario to reach them.
bowser, egg man, bowser jr, metal sonic its on the back of the sign after the other machine in that town
in adventure mode, you can't use Bowser. in free mode, you have all the characters
you have to beat them (final boss) then bowser Jr. and metal sonic (after beating eggman & bowser and after you complete all their challenges ) then beat eggman and bowser again the they will "follow" you.
