. Barney can be scaled to a feat which is
1542516.355 J while Barney's daughter can be scaled to a feat which is
0.0012 Tons of TNT or 5020800 J, meaning that Barney's daughter is about three times stronger than Barney. However, strength is not everything. Their speed difference is Susie is twice faster than baseline Subsonic, but you know Barney is not only baseline Subsonic.
While Barney may not stronger, his imagination and his experience (over 200 million years worth of experience) is something which gives him the victory, but it is not a vote to Barney as I want to wait for more input.
