The connection between the long Gamma Ray Bursts (GRBs) and Type Ic Supernovae (SNe) has revealed interesting diversity. We review the following types of the GRB-SN connection. 1) GRB-SNe: The three SNe all explode with energies much larger than those of typical SNe, thus being called Hypernovae (HNe). They are massive enough for forming black holes. 2) Non-GRB HNe/SNe: Some HNe are riot associated with GRBs. 3) XRF-SN: SN 2006aj associated with X-Ray Flash 060218 is dimmer than GRB-SNe and has very weak oxygen lines. Its progenitor mass is estimated to be small enough to form a neutron star rather than a black hole. 4) Non-SN GRB: Two nearby long GRBs were riot associated SNe. Such dark HNe have been predicted in this talk (i.e. just before the discoveries) in order to explain the origin of C-rich (hyper) metal-poor stars. This would be an important confirmation of the hypernova-first-star connection. We will show our attempt to explain the diversity in a unified manner with the jet-induced explosion model.
