The diversity in brightness and explosion energy of supernovae (SNe) that have recently been observed is remarkable. Determining the origin of unusual SNe, such as extremely faint or extremely luminous ones, or the very energetic explosions associated with GRBs (hypernovae), is very challenging. We present a core-collapse hvpernova model for the extremely luminous Type lc SN 2007bi as an alternative to the pair-instability model. We discuss how nucleosynthesis from a variety of SNe is connected to the abundance patterns of extremely metal-poor stars. Such connections may impose important constraints on the properties of the first stars, such as their evolution with mass accretion, or the asphericity of their explosions.
