He feuded with Milanito Collection a.t. and defeated him in a backup dancers deprivation match, which caused a losing streak to Milanito and occasioned the loss of his gimmick, becoming Tsutomu Oosugi. After the Animal Planets demise in 2008, Senga changed his name to Hercules Senga and abandoned his beetle traits. He reconciled with Oosugi and formed a tag team with him, known as Speed of Sounds. The two proved to be a very successful duo, wrestling  a high-speed style reminiscent of the Motor City Machine Guns or Paul London and Brian Kendrick.
