Masquerading BL Lacs (MBLLs) are an elusive class of blazars, which comprises ofFSRQs appearing as disguised BL Lac objects. In this work, we will unveil 4 suchpotential targets in an attempt to understand the nature of these sources andhow they fit in the blazar population. We propose these sources to be observedwith XMM-Newton and {it NuSTAR} to help us construct their Spectral EnergyDistributions. This will help us in revealing some essential characteristics ofthese intriguing objects.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
