Tobio

Toby (Japanese: トビオ Tobio) is a character of the day who appeared in episode 53 of Pokemon: Black & White, A Maractus Musical!. He is the Trainer of three Maractus, nicknamed "Marra" (Japanese: マーくん Maa-kun), "Racca" (Japanese: ラーくん Raa-kun), and "Tussy" (Japanese: カッチン Cacchin), who perform as the musical group the Maractus Trio (Japanese: トリオ・ザ・マラカッチ Trio the Maracacchi).

Toby wished to enter his Pokémon in a Pokémon Musical in Nimbasa City. He was on his way there when he met Ash and his friends. Toby thought that entering into the Pokémon Performance Competition would help him prepare for the Musical in Nimbasa. His ultimate goal was to get the Maractus Trio to become famous and help bring Musicals back to his hometown.

Toby made up a performance for the Maractus Trio, known as "Over the Rainbow". Marra and Racca did their parts well, but Tussy found it difficult, and the group constantly crashed to the ground as a result. Toby later had a Triple Battle with Ash to help Tussy improve its skills, but to no avail. Toby had the trio try the technique again, but Tussy failed to succeed with his part like before and ended up sending the group crashing to the ground once more.

Frustrated by Tussy's constant failures, Toby yelled at it, causing it to run away. He and Ash later found Tussy being attacked by a wild Scolipede. Toby jumped in front of Tussy and told it to run, but Tussy would not listen. Instead, Tussy jumped onto Scolipede to distract it from Toby, where it eventually jumped off and was caught by Marra and Racca, finally managing to balance on their arms in the process.

Afterwards, Toby apologized to Tussy for becoming frustrated before they all rushed to the Pokémon Performance contest, which was already underway. There, the Maractus Trio was able to perform "Over the Rainbow" without a hitch
